get directory listing

[olmos]

How can I get a list of files returned based on a file which
contains part of the file name ?

For example, I have a file which contains
test1
test2
test3

and I need to find all the files within the directory which begin with each line . I then need to input the date of the file. How can this be done with coldfusion ?


Thanks,

hi olmos,

If you know the directory name that may or may not contain the files listed in your 'file list' file, then use the steps that I have posted below.

1. read in the file that contains the other file names

<!--- You can use the function expandPath() to find the absolute path, given that the file you are reading is under your webroot. --->
<cffile action="read" file="absolute_path_to_file\filename.txt" variable="myFileContents">

2. Iterate through the results and check for the existance of file

<cfloop list="#myFileContents#" index="fname" delimiters="#chr(13)##chr(10)#">
	<cfset lookupfilePath = expandPath('.') &"\"& fname>
	<cfif fileExists(lookupfilePath)>
		<!--- Since there is no native CF way of reading lastmodified dates --->
		<!--- on files (except when using <cfdirectory>), you will need to  --->
		<!--- use something else. CFLib.org provides a ton of filesystem  --->
		<!--- functions written by fellow CFers, I've included the link below --->
		<!--- to download the source need to use the 'FileDateLastModified' function --->		
		<cfset fModDateTime = FileDateLastModified(lookupfilePath)>
	</cfif>	
</cfloop>

You can download the source for the 'FileDateLastModified()' function here:

I hope this helps,
